I am fairly new to Yii2 Rest API
I am currently using postman to test the Url of my Rest API
everything works fine until I recently added a Basic Authentication to my Code.

it now shows this message on Postman even though I added my auth key token to authorization

[
    {
        "field": "username",
        "message": "Username cannot be blank."
    },
    {
        "field": "auth_key",
        "message": "Auth Key cannot be blank."
    },
    {
        "field": "password_hash",
        "message": "Password Hash cannot be blank."
    },
    {
        "field": "email",
        "message": "Email cannot be blank."
    }
]

here is my controller under modules

<?php

namespace appmodulesv1controllers;

use yiirestActiveController;
use yiiwebController;

/**
 * ReadingSchedule controller for the `v1` module
 */
class ReadingScheduleController extends ActiveController
{
    public $modelClass="appmodelsReadingSchedule";
    
    public function behaviors() //override
    {
        $behaviors = parent::behaviors();
        $behaviors['authenticator'] = [            
            'class' => yiifiltersauthCompositeAuth::class,
            'authMethods' => [
                yiifiltersauthHttpBearerAuth::class,
                yiifiltersauthHttpBasicAuth::class,                
                [
                    'class' => yiifiltersauthCompositeAuth::class,
                ]
            ]             
            
        ];
        $behaviors['authenticator'] = [
            'class' => yiifiltersauthHttpBasicAuth::class,
            'auth' => [$this, 'auth']
        ];
        return $behaviors;
    }

    public function auth($username, $password)
    {
        return appmodelsUser::findOne(['login' => $username, 'password' => $password]);
    }



    
}

Here is mu User Module as it stated that I need to implement identity Interface

<?php

namespace appmodels;

use Yii;
use yiiwebIdentityInterface;

/**
 * This is the model class for table "user".
 *
 * @property int $id
 * @property string $username
 * @property string $auth_key
 * @property string|null $verification_token
 * @property string $password_hash
 * @property string|null $password_reset_token
 * @property string $email
 * @property int $status
 * @property string $created_at
 * @property string $updated_at
 */
class User extends yiidbActiveRecord implements IdentityInterface
{

    const STATUS_DELETED = 0;
    const STATUS_INACTIVE = 9;
    const STATUS_ACTIVE = 10;
    /**
     * {@inheritdoc}
     */
    public static function tableName()
    {
        return 'user';
    }

    /**
     * {@inheritdoc}
     */
    public function rules()
    {
        return [
            ['status', 'default', 'value' => self::STATUS_ACTIVE],
            ['status', 'in', 'range' => [self::STATUS_ACTIVE, self::STATUS_INACTIVE, self::STATUS_DELETED]],
        ];
    }

    /**
     * {@inheritdoc}
     */
    public function attributeLabels()
    {
        return [
            'id' => 'ID',
            'username' => 'Username',
            'auth_key' => 'Auth Key',
            'verification_token' => 'Verification Token',
            'password_hash' => 'Password Hash',
            'password_reset_token' => 'Password Reset Token',
            'email' => 'Email',
            'status' => 'Status',
            'created_at' => 'Created At',
            'updated_at' => 'Updated At',
        ];
    }
    public static function findIdentity($id)
    {
        return static::findOne($id);
    }

    public static function findIdentityByAccessToken($token, $type = null)
    {
        return static::findOne(['auth_key' => $token]);
    }

    public function getId()
    {
        return $this->id;
    }

    public function getAuthKey()
    {
        return $this->auth_key;  // Updated case for property name
    }
  
    public function validateAuthKey($authKey)
    {
        return $this->auth_key === $authKey;  // Updated case for property name
    }
  }
